Terang Track Drainage Remediation Works Completed

Global Rail Australia’s Track Construction Division has completed a track occupation on the Warranmbool line for V/Line Corporation, as part of their valued customers rail infrastructure upgrade program. Global Rail Australia has successfully delivered a track drainage remediation – through the installation of a new drainage system adjacent to Terang Station.

In overview, the project involved the construction of 3No new precast concrete culverts, installation of new precast concrete drainage pipe and pits and new slotted drains and construction of open shaped earth drains. Global Rail Australia’s methodology supported the delivery of all the culvert works under the tracks without the need for removal of the track. Upon installation and alignment of the culvert sections, sleepers were then installed and compacted using the excavator tamping head to achieve the line speed.

A more detailed scope of works is as follows:

• A new RCP drain at Shadforth Street (including pipe, wing, and end walls)
• A new RCP drain at Simpson Streel Level Crossing (including pit, pipe, wing, and end walls)
• Installation of new box culverts adjacent to Simpson Street (under track)
• Installation of new box culverts adjacent to station building (under track)
• Excavation and removal of existing 225mm HDPE pipe and installation of a new 450mm HDPE slotted pipe
• Reprofiling of an existing open drain adjacent to the track
• Installation of new box culverts near the end of the station platform
• Installation of new head walls to the existing HDPE pipe
• Formation of a new earth V-Drain adjacent the rail line
• Removal of spoil

Works were completed during challenging weather conditions and within a narrow occupation period, with heavy wintery conditions and continuous rainy days during the track occupation, hampering Global’s team of track experts at every opportunity.

High levels of management were therefore key, with Global Rail Australia able to call upon its multiple experienced supervisors and track engineer to plan and deliver the works and ensure the project was executed within its 12-day occupation. The project was also resourced heavily, with Global Rail Australia needing to assemble three large crews, each crew having a supervisor, with multiple labourer’s, plant operators, excavators, dumpers, small plant, and tools.

All works were satisfactorily completed in a live operational environment with no reports or incidents raised.

Global Rail Australia is delighted to have V/Line as one of its valued rail clients, is pleased to have completed this important project and look forward to more collaborative success in the future.
